Description

Technical Field

[0001] The present invention relates to the technical field of building connection, and in particular to an assembled building connection node and a connection method thereof. Background Art

[0002] With the continuous development of society and people's higher requirements for quality of life, the construction industry faces many challenges. Traditional construction methods have certain defects in time, cost and environment. As an emerging construction mode, prefabricated buildings have gradually attracted people's attention. The node connection method of prefabricated buildings is a crucial part of prefabricated buildings. At present, the mainstream connection methods are bolt connection, welding connection, mortise and tenon connection, overlap connection and prestressed connection.

[0003] Bolt connection is a common connection method in prefabricated buildings. It fastens components together with bolts, which has the advantages of easy disassembly and maintenance, and is suitable for situations where components need to be frequently replaced or moved. Bolt connection also has the problem of bolt loosening due to the inability to dissipate energy, and the resonance between components.

[0004] The welding connection method is to heat the surfaces of the interconnected components to melt them and form a connection after cooling. The welding connection method is usually used to connect thicker components such as thick plates and steel bars. It has high connection strength and stable connection effect. The welding connection method also has some disadvantages, such as difficulty in replacing components, environmental pollution during the welding process, and quality problems such as pores and cracks in the welded joints, which affect the strength of the connection.

[0005] The mortise and tenon connection method is an ancient and classic connection method, and is also a commonly used connection method in prefabricated buildings. The mortise and tenon connection method uses the shape matching of the tenon and the mortise to achieve connection through insertion and snapping. The mortise and tenon connection method has the advantages of simple structure, safety and reliability, and convenient disassembly and maintenance. In prefabricated buildings, the mortise and tenon connection method is often used to connect wooden components or plate components. In practical applications, the mortise and tenon connection method needs to consider the dimensional accuracy of the tenon and the mortise and the processing of the connection surface. The processing accuracy of the tenon and the mortise directly affects the quality and stability of the connection, so it needs to be processed very finely and is complex.

[0006] The core principle of the overlap connection method is to achieve the purpose of connection by designing the structure of the overlapped parts so that they can fit together. The overlap connection method can be divided into two forms: direct overlap and indirect overlap. The overlap connection method has the advantages of easy installation, easy disassembly and maintenance, and strong bearing capacity, but in some special cases, it may have disadvantages such as insufficient structural stability and poor fire resistance. Therefore, when choosing the overlap connection method, it is necessary to comprehensively consider factors such as the shape, size, bearing capacity requirements and use environment of the components.

[0007] The prestressed connection method is to increase the bearing capacity and stability of the component by adding prestressed steel strands to the component. The main features of the prestressed connection method include improving the overall performance and seismic performance of the structure, reducing the deformation and cracks of the component, and reducing the deadweight and thickness of the component. The prestressed connection method also has some disadvantages, such as great construction difficulty, high cost, and high requirements for construction technology.

[0008] Therefore, there is an urgent need for a connection node structure that is simple in structure and easy to use. Summary of the invention

[0009] The purpose of the present invention is to provide an assembled building connection node and a connection method thereof to solve the above-mentioned technical problems, and the node has the advantages of simple structure, easy use and stable connection.

[0010] To achieve the above-mentioned purpose, the present invention provides an assembled building connection node, including a shell, one end of which is provided with an opening, a cover for sealing the opening is provided at the opening, the cover is slidably connected to the shell, the interior of the shell is filled with a non-Newtonian fluid, and the inner surface of the cover is in contact with the non-Newtonian fluid; two components to be connected are connected by a connecting structure provided on the shell, the outer surface of the cover is in contact with the surface of one component to be connected, and the bottom of the shell is in contact with the surface of the other component to be connected.

[0011] Preferably, the shell is a cubic metal shell.

[0012] Preferably, the edge of the cover is provided with a horizontal folded edge folded outward, and the folded edge and the cover are connected to form an integral structure via an inclined surface.

[0013] Preferably, the folded edge of the cover is located inside the shell, and the folded edge is located below the opening.

[0014] Preferably, the size of the folded edge is larger than the size of the opening.

[0015] Preferably, the connection structure includes a sleeve, which is evenly distributed around the opening, a mounting hole penetrating the shell is provided on the shell, the sleeve is inserted into the mounting hole, the sleeve is sealed and fixedly connected to the shell, and a bolt is provided in the sleeve to connect the two components to be connected.

[0016] Preferably, the sleeve is a metal sleeve, and the bottom end of the sleeve is flush with the bottom surface of the shell.

[0017] Preferably, a gasket is provided on the top surface of the sleeve.

[0018] Preferably, the top surface of the cover protrudes from the shell, and the height of the top surface of the cover is not lower than the height of the gasket.

[0019] The connection method of the above-mentioned prefabricated building connection node comprises the following steps: S1. Pour the non-Newtonian fluid into the shell, insert the cover into the shell through the opening, and press the cover above the non-Newtonian fluid. The height of the cover is higher than the height of the gasket. S2, contacting the cover with the surface of one component to be connected, and contacting the bottom of the shell with the surface of another component to be connected; S3. Bolts are passed through the sleeve and the components to be connected, and the bolts are tightened to connect the two components to be connected through the connection node. After connection, the outer surface of the cover is flush with the outer surface of the gasket.

[0020] Therefore, the advantages and positive effects of the prefabricated building connection node and the connection method thereof described in the present invention are: 1. The shell is filled with non-Newtonian fluid, which has the characteristics of being stronger when it meets strong forces and weaker when it meets weak forces. When the component is subjected to a relatively slow external force, the non-Newtonian fluid deforms, thereby consuming part of the energy and better protecting the component connection structure. When the component is subjected to a large and rapid force, the non-Newtonian fluid hardens and transmits the force of the beam and column components to the foundation components in a timely manner, better protecting the building component structure. Non-Newtonian fluid avoids direct contact between components, can avoid resonance between components, and reduce the harm of resonance to components.

[0021] 2. The edge of the cover is provided with a horizontal folded edge that folds outward, and the folded edge and the cover are connected to form an integral structure through an inclined surface. The folded edge overlaps the bottom of the shell to achieve an outward convex and inward buckle connection of the cover, so that the cover can always be in close contact with the surface of the component to be connected under the action of the non-Newtonian fluid. The cover is set at the opening of the shell, and the cover can move inside the shell to adapt to the volume change of the non-Newtonian fluid, so that the cover is always in contact with the surface of the component to be connected under the action of the non-Newtonian fluid, ensuring the timely transmission of force between the components.

[0022] 3. The cover seals the non-Newtonian fluid inside the shell, reducing the contact between the non-Newtonian fluid and the external environment, alleviating the impact of the external environment on the non-Newtonian fluid, and increasing the life of the non-Newtonian fluid.

[0023] 4. A connection structure is arranged on the shell, and the connection structure includes a sleeve, and bolts are arranged in the sleeve to connect two components to be connected. The two components to be connected are connected by bolts to improve the stability of the connection, and the sleeve separates the non-Newtonian fluid from the bolt, which facilitates the installation and disassembly of the bolt in the sleeve, and is conducive to the reuse of the connection node.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown. An assembled building connection node includes a shell 1, which is a cubic metal shell 1. The exterior of the shell 1 is treated with anti-corrosion by spraying an anti-corrosion coating or the like. The shell 1 can be made of an existing steel sheet. An opening 6 is provided at one end of the shell 1, and the opening 6 is a rectangular opening. The provision of the opening 6 facilitates the addition of a non-Newtonian fluid 3 into the shell 1. A cover 2 is provided at the opening 6 to seal the opening 6, and the cover 2 is slidably connected to the shell 1, and the cover 2 and the shell 1 are in contact with two components to be connected respectively. The interior of the shell 1 is filled with a non-Newtonian fluid 3, and the inner surface of the cover 2 is in contact with the non-Newtonian fluid 3. The cover 2 is also used to seal the non-Newtonian fluid 3 inside the shell 1, reduce the contact of the non-Newtonian fluid 3 with the external environment, reduce the impact of the external environment on the non-Newtonian fluid 3, and increase the life of the non-Newtonian fluid 3.

[0030] The non-Newtonian fluid 3 has the characteristics of being stronger when it meets strong forces and weaker when it meets weak forces. When the component is subjected to a relatively slow external force, the non-Newtonian fluid 3 deforms, thereby consuming a portion of the energy and better protecting the component connection structure. When the component is subjected to a large and rapid force, the non-Newtonian fluid 3 hardens, and the force of the beam-column component is promptly transmitted to the foundation component, thereby better protecting the building component structure. The non-Newtonian fluid 3 avoids direct contact between components, can avoid resonance between components, and reduce the harm of resonance to components.

[0031] like Figure 6 , Figure 7 , Figure 8 As shown. The edge of the cover 2 is provided with a horizontal folded edge 7 folded outward, and the folded edge 7 and the cover 2 are connected to form an integral structure through an inclined surface 8. The folded edge 7 of the cover 2 is located inside the shell 1, and the folded edge 7 is located below the opening 6. The size of the folded edge 7 is larger than the size of the opening 6, so that the folded edge 7 overlaps with the bottom of the shell 1, realizing the outer convex and inner buckle connection of the cover 2, so that the cover 2 can always be in close contact with the surface of the component to be connected under the action of the non-Newtonian fluid 3. The cover 2 is set at the opening 6 of the shell 1, and the cover 2 can move inside the shell 1 to adapt to the volume change of the non-Newtonian fluid 3, so that the cover 2 is always in contact with the surface of the component to be connected under the action of the non-Newtonian fluid 3.

[0032] The two components to be connected are connected by a connection structure provided on the shell 1. The connection structure includes a sleeve 4, which is a cylindrical metal sleeve 4. The sleeves 4 are evenly distributed around the opening 6. In this embodiment, three sleeves 4 are respectively provided on the four sides of the opening 6. The shell 1 is provided with a mounting hole that penetrates the shell 1, and the sleeve 4 is inserted in the mounting hole. The sleeve 4 is fixedly connected to the shell 1 by welding and sealing. Bolts for connecting the two components to be connected are provided in the sleeve 4. The sleeve 4 is used to separate the non-Newtonian fluid 3 from the bolt, which facilitates the installation and disassembly of the bolt in the sleeve 4 and is conducive to the reuse of the connection node.

[0033] The top surface of the sleeve 4 is provided with a gasket 5, which is a rubber buffer gasket 5. The bottom end of the sleeve 4 is flush with the bottom surface of the shell 1. The top surface of the cover 2 protrudes from the shell 1, and the height of the top surface of the cover 2 is not lower than the height of the gasket 5, so that the cover 2 is in close contact with the surface of the component to be connected under the action of the non-Newtonian fluid 3. After the connection node is installed, the outer surface of the cover 2 is in contact with the surface of one component to be connected, and the bottom of the shell 1 is in contact with the surface of the other component to be connected.

[0034] The connection method of the above-mentioned prefabricated building connection node comprises the following steps: S1. Pour the non-Newtonian fluid 3 into the shell 1, insert the cover 2 into the shell 1 through the opening 6, and press the cover 2 onto the non-Newtonian fluid 3. The height of the cover 2 is higher than the height of the gasket 5.

[0035] S2. The cover 2 is brought into contact with the surface of one component to be connected, and the bottom of the housing 1 is brought into contact with the surface of another component to be connected.

[0036] S3. Bolts are passed through the sleeve 4 and the components to be connected, and the bolts are tightened to connect the two components to be connected through the connection node. After the connection, the outer surface of the cover 2 is flush with the outer surface of the gasket 5.

[0037] Therefore, the prefabricated building connection node and the connection method thereof described in the present invention have the advantages of simple structure, convenient use, and stable connection; and can effectively reduce the harm caused by resonance between components.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
